GFDL experiment name = CM2Q-d2_1861-2000-AllForc_h3. PCMDI experiment name = 20C3M (run3). Initial conditions for this experiment were taken from 1 January of year 151 of the 1860 control model experiment named CM2Q_Control-1860_d2. Several forcing agents varied during the 140 year duration of the CM2Q-d2_1861-2000-AllForc_h3 experiment in a manner based upon observations and reconstructions for the late 19th and 20th centuries. The time varying forcing agents were atmospheric CO2, CH4, N2O, halons, tropospheric and stratospheric O3, anthropogenic tropospheric sulfates, black and organic carbon, volcanic aerosols, solar irradiance, and the distribution of land cover types. The direct effect of tropospheric aerosols is calculated by the model, but not the indirect effects.

The GFDL Data Portal (http://nomads.gfdl.noaa.gov/) provides access to NOAA/GFDL's publicly available model input and output data sets. From this web site one can view and download data sets and documentation, including those related to the GFDL CM2.0 model experiments run for the IPCC's 4th Assessment Report and the US CCSP.

Geophysical Fluid Dynamics Laboratory (GFDL) CM2.0, 20C3M (run 3) climate of the 20th Century experiment (20C3M) output for Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) and US Climate Change Science Program (CCSP).
